CLEANING ATTACHMENT FOR TOBACCO PIPES.

Application filed April 23, 1925.

This invention relates to tobacco pipes, and the main object of the invention is to generally. improve pipes of this class.

A further. object of the invention is to provide lneans between the pipe bowl and the mouthpiece for arresting the passage of condensation from the bowl towards the mouthpiece and also arrest the passage of saliva and condensed moisture from the mouthpiece into the bowl, and to include in the arresting means a removable cleaner or scraper operating to remove all sediment or foreign matter when the cleaner or scraper is withdrawn.

A further object of the invention is to provide in association with a cleaning and scraping means between the bowl stem and mouthpiece of a tobacco pipe an accessory or element that will prevent slugs or particles tobacco from being drawn from the bowl into the mouth, and also prevent saliva from reaching the pipe bowl and at the same time permit the use of a mouthpiece and pipe stem cleaner of the usual type.

A further object of the invention is to provide in connection with the stem of a tobacco pipe bowl and mouthpiece a general construction which will be materially advantageous in'the application and use of the improved cleaning means to effect a more thorough removal of the sediment and moisture that may lodge in the bowl stem and also render the improved structure more strong and durable in its service.

A still further object of the invention is to interpose a removable cleaner between the stem of a tobacco pipe bowl and the mouthpiece that is so constructed that it may be used for scraping and cleaning the interior of the bowl.

With the foregoing and other objects and advantages in view, the invention consists in the preferred construction and arrangement of the several parts which will be more fully hereinafter described and claimed.

In the drawings Fig. 1 is a longitudinal vertical section of a tobacco pipe and its stemland mouthpiece, showing the features of the invention applied thereto.

Fi 2 is aside elevation of a pipe bowl and its stem and mouthpiece together with the improved cleaning and other features of the invention a plied thereto, themouthpiece being shown etached from the bowl stem.

6 is a mouthpiece 8, and this mouthpiece as well as the bowl 5 and'stem 6 may be of any suitable materials or those commonly employed in tobacco pipe construction. The smoke bore 7 of the stem 6 is diametrically enlarged to form a cylindrical chamber 9 and is provided with acylindrical liner 10 of metal or other suitable material, presenting an inner smooth wall or surface. The chamber 9 extends fully through the rear end of the stem 6 and the liner 10 terminates coincidently with the said rear end of the stem, and adjacent to the forward terminal of the chamber 9 the smoke bore or passage 7 is slightly enlarged, as at 11, to provide a seat for a purpose which will be presently explained. The bore of the mouthpiece 8 at its inner end is also enlarged, as at 12, to form a socket to receive the rear extremity of a portion of the improved features.

The improved features comprise a tubular stem or smoke conduit 13, which extends from the point of communication of the bore 7 with the base of the cavity or chamber l l of the bowl 5 and rearwardly through the center'of the chamber 9 to a point slightv ly outwardly from the rear terminal of the stem 6. The forward extremity of the tubular stem or smoke conduit 13 is held in normal position or prevented from being projected beyond a certain predetermined extent through the stem 6 by a stop collar 15 and washer 1.6, which respectively engage against the forward end wall of the chamber 9 and the seat 11. the said stop collar 15 and washer 16 being secured to the stem or conduit 13. The rear end of the stem or conduit 13 is formed with a downwardly bent or deflected lip or guard 17, which stands a distance away from the rear outlet of the said stem or conduit 13. The purpose of the stem or conduit 13 with its rear lip or guard 17 is to permit free passage of the smoke from the pipe bowl through the stem 6 and rearwardly through the mouth piece 7 and at the sam time prevent slugs or particles of tobacco from passing beyond the rear end of the same, the lip or guard 17 operating to deflect or throw the tobacco particles or slugs that may pass through the said stem or conduit 13 downwardly into the lower portion of the forward extremity of the mouthpiece or into a part of the cleaner, which consists of arear tubular body or holder 18 having rods or wires 19 secured therein at diametrically opposite points and extending beyond the front terminal of the said tubular body or holder and secured to a dished cleaning disk 20 having a central opening 21, to permit the stem or conduit 13 to pass therethrough. The dished cleaning disk 20 has a rear reduced scraping edge 22, and'the diameter of this disk 20 is such as to have a sliding fit in the liner 10 but at the same time have its reduced edge closely engaging the inner wall of said. liner. The tubular body or holder 18 may also serve as a convenient grippingn'ieans, and further, as a frictional connecting means between the pipe stem and mouthpiece of the pipe, the tubular holder in this latter function providing a tight joint between the mouthpiece and stem of the pipe. The cleaner as just explained I is removably fitted in the chamber 9 and the dished cleaning disk 20 directly engages the liner 10, and when the said cleaning attachment is fully applied, the disk or head 20 is in engagement with the central portion of the stop collar 15 and a portion of the combined holder and grip projects rearwardly from the rearend of the stem 6 and is enclosed within ant frictionally engages the wall of the socket 12 at the forward end of the mouthpiece 8, and thereby also serves as a joint means for the separable attachment of the said mouthpiece relatively to the rear end of the stem 6. hen the smoke stem or conduit 13 and the cleaner as specified are fully assembled in the stem 6 and mouthpiece 8, the said parts will be closely associated as shown by Fig. 1. lVhen it is desired to clean the stem 6, the mouthpiece S and the body or holder 18 and disk 20 are withdrawn, thus pulling the cleaning disk or head 20 rearwardly through the liner 10 and removing all moisture and tobacco accumulations that may have lodged within the latter. After the disk or head 20 has been removed, the accumulations that may 7 be withdrawn therewith and lodged thereon can then be removed and the said cleaning attachment re-inserted in the liner 10 as shown by Fig. 1. When the cleaning attachment has been withdrawn, the stem or smoke-conveying conduit may also be withdrawn by catching hold of the rear projecting extremity thereof and accumulations therein may then be readily removed in any suitable manner, and said stem and smoke conduit afterwards re-applied as shown. When the parts are all closely assembled and enclosed within the stem 6 and mouthpiece 8, no portion of the same is exterior-1y exposed, and the rear portion of the combined holder and gripping means 18 will receive any particles or slugs passing from the cavity 14 ofthe pipe bowl 5 rearwardly therethrough and deflected downwardly by the lip or guard 17, and such particles or slugs may be removed when the said cleaning attachment is withdrawn from the stem 6.

In adcitionto the functions of the cleaning attachment as above explained, it may also be used for cleaning the pipe bowl as illustrated by Fig. 4, and in this particular service the mouthpiece 8 is grasped and serves as a handle, and the reduced edge of the disk or head 20 is caused to travcrse the wall of the cavity 1st by manually reciprocating the same, and thereby loosen or scrape off any accumulations that may adhere to the wall of the bowl cavity.

It is proposed to employ such materials in the construction of the several parts of the attachment as may be best adapted for the purpose and which will not be affected by the tobacco accumulations and moisture that may aggregate or pass into the liner 10, either from the pipe bowl or forwardly through the mouthpiece. The liner 10 in addition to presenting a smooth wall for the effective operation of the cleaning attachment also serves to prevent wear on the n'iaterial of the stem 6, and further serves as a means for accurately seating and guiding the cleaning attachment in its application and operation. If it is desired to use the ordinary form of pipe cleaner for the stem or conduit 13, the same may be readily inserted in the stem or conduit, as the lip or guard 17 does not obstruct the rear open end of the latter stem or guard, sufficient space being left between the lip or guard and rear end of the stem or conduit to permit the insertion of the end of the cleaner.

The improved cleaning attachment and the stem or conduit 13 are of such comparatively simple form as to be readily appli cable to pipe bowl stems 6 and mouthpieces S of pipes now in use or completed in their usualform by a very simple modification of the original construction of such pipes already produced. It is obvious that pipes now completed in construction or on the market may have their stems suitably bored to form the chamber 9 and seat- 11 of the stem structure 6 thereof, and the mouth pieces may also be bored to form sockets similar to the socket 12. Such modification would necessitate very little expense, and it is therefore proposed to construct the i111- proved cleaning attachmentand smoke stem or conduit and the liner 1O ready for application to pipes now in use or on the market.

Changes in the proportions, dimensions and minor details may be adopted without departing from the nature or spirit of the invention.

lVhat is claimed as new is 1. A cleaner for a tobacco pipe comprising a combined tubular holder and grip means having forwardly projecting connecting rods secured to a disk head of dished form with a reduced scraping edge, and tubular means with a stop collar thereon at an intermediate point to re ulate the placement of said tubular means relatively to a pipe stem and bowl, the tubular means projecting through the disk head and terminating at the rear within the holder.

2. A cleaner for a tobacco pipe, consisting of the combination with the stem of the pipe, of a tubular holder and grip means having connecting means projecting forwardly therefrom with an open space thereb-etween and a disk head of dished form positively held by said connecting means in advance of the forward end of the holder and rip means, the dished disk head having a scraping edge, and a tubular conduit held at its forward extremity in a part of the stem and projecting through the center of the disk head rearwardly to and terminating within the holder and grip means in advance of the rear end, the holder With the disk head being readily separable and removable from the pipe stem and the conduit and useable as a means for cleaning the pipe bowl.

3. A cleaning attachment for tobacco pipes, comprising a tubular holder and a dished disk head held in fixed position relatively to and in advance of the tubular holder and having a rear reduced scraping edge and a central opening, and a tubular smoke conduit having stop means thereon and a guard lip spaced from the rear open extremity thereof, the said disk head being movable over the conduit.

4. A cleaning attachment for tobacco pipes comprising a tubular holder and a dish-ed disk head held in fixed position relatively to and in advance of the front end of the tubular holder and having a rear reduced scraping edge, and a smoke conduit of relatively small diameter having stop means thereon and centrally inserted through the said disk head and normally terminating at its rear extremity within the length of the tubular holder, the disk head with the tubular holder being longitudinally movable with relation to the said conduit.

5. A tobacco pipe having a stem with a smoke bore communicating withthe lower portion of the cavity of the bowl and also with a diametrically enlarged chamber and a mouthpiece, a liner within the chamber extending fully from the forward end of the latter to the rear terminal of the stem, a tubular smoke conduit removably mounted in the bore and chamber and projecting slightly beyond the rear end of the stem, a cleaning attachment comprising a tubular holder frictionally held in the forward end of the mouthpiece and having rods extendingtherefrom and connected to a dished. disk head with a rear reduced scraping edge and a central opening to fit over the said conduit, the holder and dished head being respectively insertable and enclosed within the liner over the conduit and within the rear extremity of the stem and forward end of the mouthpiece.

In testimony whereof I have hereunto set my hand.
